Application filed January 30,1905. Serial No. 243,221.

To all whont it may concern:

Be it known that I, LORING GOES, a citizen of the United States, residing at \Vorcester, in the county of IVorcester and State of Massachusetts, have invented a new and useful Continuous Milling-h Iachine, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this inventionappertains to make and use the same.

The prime object of my present invention is to provide a practically efficient and convenient mechanism adapted for milling the heads and jaws of wrenches and other analogous class of work quickly, accurately, and economically and adapted for a continuous operation, as hereinafter more fully explained.

Another object is to provide a milling-machine of the character specified having a dualfaced carrier-disk wheel, in combination with a plurality of milling-tool operators, whereby the mechanism is adapted for simultaneous operation at the opposite faces of the disk upon two lines of work.

Minor objects and features of my invention are pointed out and explained in the following detailed description, the particular subjectmatter claimed being hereinafter definitely specified.

In the accompanying drawings, Figure 1 represents an end view of a mechanism embodying my invention. Fig. 2 is a rearview of the same. Fig. 3 is a plan view with some of the parts shown in horizontal section. Figs. I and 5 are fragmentary views showing the manner of connecting the adjusting bearinghead with the main standing frame. Fig. 6 is a diagrammatic view of the carrier, millingcutters, Sac. Fig. 7 is a front detail view of the work-holding device. Fig. 8 is a transverse section of the segmental rim-plate or vise-section, and Fig. 9 is a bottom View of one of the clamp-pieces.

The mechanism embodying my invention comprises a circular work-supporting carrier supported on an axial shaft that is rotatable in suitable bearings on the main uprights or standing frames. The periphery of the carrier is provided with a toothed or worm-gear flange fixed to or formed integral thereon, the teeth of which mesh with a driving-gear or worm-screw mounted on a rotatable shaft, and by means of which worm-gearing the carrier is revolved with a steady powerful movement In referrin to the drawings, C indicates a the carrier, mounted on the shaft 2, which is rotatable in hearings on the main upright frames (1, that stand upon the bed A. This carrier consists of a disk wheel, dual-faced and provided with the peripheral worm-gear 3 for meshing with the worm 4 on the feedshaft F and with annular rim-faces 0, each having therein a circular undercut T-groove 7. Firmly mounted upon the carrier-disk rim on each of its lateral faces there is provided removable segments or annulus-sections 5, formed with a series of seats or matrices for supporting the wrenches or work W, and there are also provided clamping devices 6, by which the work can be securely fixed in position thereon and released, as occasion may require.

The preferred construction of the vise plate or section 5 is best shown in Figs. 6, 7, and 8. A cavity or matrix at is formed in the plate 5, with a space n to accommodate the wrenchjaw strap and a flat seat and shoulder it, against which the flat side and angle of the wrench-bar \V can rest. A guard-pin! is erected in the cavity to keep the wrench-bar back against the shoulder. The clamp devices 6 consist of slotted pieces (see Fig. 9) having bearing-faces v on the under side adjacent to its ends. Said pieces are attached to the segmental plate 5 in pairs. each by a bolt d, passing through the slot 8 and thread- I ed into the plate in such manner that the end of the piece can be clamped down upon the wrench-bar, as in Fig. 7, or when the screw or bolt (1 is loosened the piece can be slipped back to release the wrench-bar without detaching the clamp-piece from the plate 5.

The vise-sections can be formed as segments of any convenient parts of the circle. They are retained on the carrier by a countermatching rib t and T-headed bolts 8, that engage with the T-groove 7 as shown in section Fig. 8. The wrenches or articles to be milled are held with their heads projecting inward toward the axis and fiatwise with the plane of the carrier. These vise-sections can be taken from the carrier-wheel and replaced by others having matrices, seats, or clamping means adapted for supporting wrenches or articles of different size or shape.

The milling-cutters 9 and the cutter-operating mechanisms at the right and the left of the carrier are in the instance shown made of similar construction, but in right and left order. A description of one set will apply to either. The arbor 10, carrying the milling-cutters 9, is mounted to rotate in bearings respectively disposed on a bearing-head 12 and on a projecting arm 13 of the frame. Below the arbor and parallel therewith there is an operating-shaft 14:, having a pulley 15 keyed thereon and also a pinion 16, that meshes with a gear 17 fixed on the milling-tool arbor. The inner end of the arbor 10 is fitted for supporting and rotating the milling-cutters and provided with means, as a clamp-nut, for securing them rigidly thereon.

with the carrier-flange.

The bearing-head 12 is adjustably connected with the main-frame in a manner to adjust.

laterally thereon by suitable countermatching seating-surfaces 18 and T-grooves 19 for the heads of the attaching-bolts, and a rack 20 and pinion 21 or other suitable devices are provided for shifting the position of the bearing-head. As best shown in Fig. 2,the toothed rack is arranged on the bearing-head, and the rotatable pinion having a key-stem or means for turning it is mounted in connection with the frame.

When the attaching-bolts Z) are loosened, the bearing-head 12, together with the arbor 10, gears 17, shaft 14, and milling-cutters 9, can by the aid of a key or wrench on the pinion-stem be moved laterally away from the carrier, so as to facilitate the adjustment, removal, and changing of the milling cutters or tools at the inner end of the arbor. When such movement is effected, the arbor 10 and there is a rigid upright standard 27, fixed to the bed and having thereon at its upper end an adjustable brace-bearing 28, that rests against the feed-shaft adjacent to the Wormscrew 4: for keeping the same firmly in mesh The degree of presters while they are in operation.

sure of said brace-bearing can be regulated by means of a screw 29, arranged at the back of said bearing, as indicated on Fig. 1.

The bed-frame A is best formed as a basin with a channel for catching the lubricating liquid and a pump 30, provided for raising said liquid from the channel in the bed to a reservoir 31, arranged overhead and from which a pipe or pipes 32 extend for delivering a stream of such liquid to the milling-cut- The delivery-opening of the pipes 32 is preferably upward between the pairs of milling-cutters 9. (See Figs. 2 and 6.) are arranged in the pipes for regulating the quantity of lubricating liquid delivered therethrough. The pump may be operated by any suitable meansas, for instance, a revolving crank 34 on a shaft havingapulley 36 for its rotation.

The motive power for operating the mechanism may be transmitted from any suitable source by belts running .on the pulleys 15, 22, and 36 or by such means as may in any particular instance be convenient or desired.

Preparatory to milling the headed wrenchbar and its slidingjaw are assembled, as indicated, so as to be both milled by one operation.

In the operation the milling-cutters 9 being in rapid action and the carrier (J slowly revolving in the direction indicated by arrow on Fig. 1 then the attendant at the front of the machine introduces the wrenches or articles WV to be milled into the vise-plate seats at the position I and clamps them in position, first removing the finished work W, if such is contained therein. The movement of the carrier C continuously brings the several wrenches to the milling-cutters and passes them in consecutive order between the pair of Suitable stop-cocks 33' cutters 9, thereby simultaneously milling off the two opposite sides of the two wrench-jaws in a uniform and efficient manner and also operating upon two series of articles at the same time, one series on the right and one on the left side of the carrier-rim. The machine operates continuously, as the removal and introduction of the work is performed without stopping the carrier.

The machine as herein illustrated and preferably is made with a dual-faced carrier and two sets of milling appliances for simultaneously operating u pontwo series ofwrenches; but it is obvious that my invention is in like manner applicable in a machine wherein the carrier is made with but a single face or for carrying and milling only a single series of wrenches.

I am aware that differently-constructed revoluble devices have beenemployed in millingmachines for holding and advancing work to milling cutters or tools, and I do not, therefore, claim the broad idea of revolubility in an appliance for such purpose nor the operation IIO ISO

irrespective of the construction and mode of combination of the mechanism.
